Pex Pipe for Underfloor Heating

What is PEX Pipe?

PEX is cross-linked polyethylene. Through one of several processes, links between polyethylene molecules are formed to create bridges (thus the term 'cross-linked'). This resulting material is more durable under temperature extremes, chemical attack, and better resists creep deformation, making PEX an excellent material for underfloor heating and hot water applications.

How long has PEX Pipe been used?

PEX was developed in the 1960's. PEX tubing has been in use in many European countries for plumbing, underfloor heating and snow melt applications since that time. PEX was introduced in the United States in the 1980's, and has seen significant growth in market demand and production.

What are recommended uses for PEX Pipe?

PEX's flexibility and strength at temperatures ranging from below freezing up to 200 degrees Fahrenheit makes it an ideal piping material for hot and cold water plumbing systems, service lines, underfloor heating systems, snow melting applications, ice rinks and refrigeration warehouses.

Can PEX Pipe be used under the slab?

Yes. The flexibility of PEX allows it to be supplied in coils meaning installations under the slab can be made in a single, continuous length without the need for fittings. PEX is not affected by concrete, (it is commonly encased in concrete for radiant floor heating). PEX, however, must be sleeved when penetrating a slab.

How are PEX Pipe systems tested for leaks?

PEX plumbing and radiant heating systems can be pressure tested using water to check for leaks. Follow manufacturer's instructions.

Is the thermal expansion/contraction of PEX Pipe a problem?

No. While PEX expands more than other plumbing materials, directional changes made with the tubing and some slack in the tubing during installation accommodate the expansion and contraction of the system if properly installed.

Is PEX Pipe freeze-break resistant?

PEX piping is freeze damage resistant and can expand and contract as water freezes and thaws within the tubing. No tubing material is freeze-break proof, however, and PEX should be installed using the same locally-prescribed insulation requirements to prevent freezing of any plumbing system.

Can PEX Pipe be joined with solvent cement?

No. PEX cannot be joined with solvent cement, glues or heat fusion. PEX is installed using only mechanical fittings or compression fittings.
